Why the mapped width of an earthquake zone is far wider than the fault that causes it How satellite altimetry measures the height of the ocean to the centimetre How accurate is a phone GPS fix in a canyon of glass towers UTM zones vs latitudes and longitudes: why surveyors work in metres instead of degrees How a meridian is marked and resurveyed on the ground with geodetic monuments Why the same coordinates land in different places on WGS84 and NAD83 How to keep a latitude column from turning into dates and scientific notation in a spreadsheet Changing a map datum can shift every coordinate by hundreds of metres How does a GNSS receiver work out your position from satellites that only broadcast time? Why three satellites are not enough to fix your position on the ground Decimal degrees vs degrees minutes seconds: which format surveyors and hikers each prefer How many decimal places in a coordinate actually matter before the extra digits are noise How is area computed on a curved Earth without distorting the total Why a country's land area changes depending on who measured it A degree of longitude shrinks toward the poles while a degree of latitude stays the same
